Specification of Lettei s Patent.

Patented Ma. 28, 1916.

Application filed March 15 1912, Serial No. 683,937. Renewed February 23, 1915. Serial No. 10,123.

To all whom it may concern Be it known that I, J oNs ject of the King of Sweden, and a resident of New York city, in'the county of New- A further object is to provide a tire andwheel construction comprising-means for fastening the tire to the felly of the wheel.

The novel features of construction will be set forth in the claims.

Referring to the drawings which form a part of this specification Figure 1 is a side elevational view of a wheel and tire embodying my invention. Fig. 2 is a cross sectional View of a tire and wheel felly, disclosing one form 'of crosssection, the folds of the rubber being practically of even thickness. Fig. 3 is a similar view showing a tread surface of the non-skid type and modified form of construction. Fig. 4 is a cross sectional view of a form in which a.

shoe is used in combination with the form as shown in Fig. 2, from the dotted l1nes upward. Fig. 5 is a cross sectional view of a tire comprising a plurality of folds, each fold of which presents a tread surface to the inner tread surface of the shoe, or if used without the shoe, presents said surface direct to the roadway. Fig. 6 is a cross sectional view of a tire of modified construction and adapted to carry-heavier loads than that disclosed in Fig. 21 Fig. 7 1s a cross sectional view of a form similar to that shown in Fig. 6, but having a single annular chamber formed therein. Fig. 8 is across sectional view of a modified form of that-shown in Figs. 6 and 7. Fig. 9 is a cross sectional view of a modified "construction to that disclosed in Fig. 5.

MoNsoN, a sub- Referring to Figs. 1, 2 and 3, A, indicates the felly of a wheel on which is mounted ,an iron or other suitable inelastic band, B,

the outer edges B of which are rounded over to present a smooth surface, and the middle portion of which is preferably curved as illustrated at B C, indicates the tire which is made of rubber or'oth'er suitable yielding material. -When made of rubber, the tire is made by a mold in the usual manner,,the spaces C and C being formed by inserting a core in the mold which is made very thin at the point where the sides C and C are shown to abut at Ci in order to support the core portion which forms the space C The spaces 0 and C extend entirely around the circumference of the tire and the sections C and C are held in abutting relation at C by the flanges D.

The walls of the tire are preferably formed of equal thickness down to the felly,

as shown in Fig. -2, but not necessarily so. The curving of the side walls inward and then outward as shown at C form shoul ders C, over which the outer inwardly curved edge portions D of the flanges project to assist in holding the tire to the wheel felly. The portions C extend around and below band B where they are increased in thickness, and abut the sides of the felly as shown. The side clamps extend over the portions C and abut the felly and are held thereto by bolt and nut construction illustrated at E. The walls contact the periphcry of the band adjacent to its edges and curve with gradual convex curves C up to their abutting line 'of contact C. With this construction, the initial stress on the tread tends to bend the rubber and cause it to seat farther upon the band. Added stress upon the tread will cause a compressio'n of the rubber or elastic material and that offered to the initial stress.

The non-skid tread surface is illustrated at F in Fig. 3. The length of contact of 1 the abutting surfaces CF in Fi 3 are shown thus giving rise to a greater resistance than vided and amiddle bearing or abutting surjust described and that shown in Fig. 6 is, that the outer surface of the side walls is not curved inward as illustrated at C in Fig. 2, but presents straight parallel sides, and the side clamps are formed without the curved portions D. The space C is of greater area than space C and the under side C of the curved wall is formed lower and of less radius than that of the wall C thus makirig a stifi'er construction than that shown'in Fig. 2, and more suitable for carrying aheavy load where the width of the tires are the same. The walls are noticeably thicker in the construction shown in Fig. 6 than as-shown in Fig. 2, and this also would add strength and stifiness to the tire.

Referring now to Figs. 4 and 5, it will be seen that the tire disclosed in Fig. 2 as shown down'to the dotted lines ZZ, is inclosed in a shoe ,G, the inner edges of said sh oe being formed in the same shape as the inner edge portions G of the tire shown in Fig. 2, and thus holding the inner" tire portion securely in place. By this construction, the shoe may be wornout-and replaced with a new one and the inner portion used again. By using the conformation of elastic walls described "in connection with Figs. 1 to 3, a similar action is obtained in resisting stress upon the tread, as above described.

In'Fig. 5, I illustrate the inner portion H as formed with a double tread or divided tread indicated by H and H and by reason of their being joined together or abutting on the dotted line X-X, as may bepreferred, a central inner bearing H is. proface H is also provided, the effect of which is to form cooperative support laterally. A s'hoe G, similar in construction to shoe G in Fig. 4,.is provided to hold the inner portions in proper position. The thickness of the walls of the portion H are practically uniform but may be modified in this respect without departing from the scope of my invention.

n Will 1.. obvious to thOSe skilled in this art that my invention resides primarily in the shape of the inner sides of the walls of the tire so formed as to present an annular space or spaces extending circumferentially of the tire as illustrated and having one or more abutting surfaces which form the partition or partitions between said chambers or spaces, and next, in forming the exterior surfaces so that pressure against the tread will be transmitted to the abutting surfaces, which surfaces are more or less-curved.

Referring now to the constructions shown in Figs. 7 and 8; Fig. 7 is'the same construction as that shown and described in Fig. 6, except the outer annular chamber C is dispensed with, but the tire section is divided or parted up to about the same point C in the tire, thereby providing a longer abutting surface between the side portions.

In the construction disclosed in Fig. 8, the outer chamber is dispensed with. and the tire divided up to the point C thus providingv tire sections of about equal thickness. The tire is also provided with an inner band .I, located at the bottom of the annular chamber C and the inner edge portions J and J are united together alo'ngthe dotted line J beneath the band I and therefore the tire as a whole is mounted outside-of the my invention, I claim as new 1.
